Caption: Light micrograph of hexagonal facets, called ommatidia, which form the compound eye of a dragonfly. The compound eye is a characteristic of insects, although the size, shape & number of facets varies among species. The dragonfly with 30,000 facets, has the largest insect eye. Each ommatidia is a light sensitive unit consisting of a lens immediately behind the cuticular surface & light sensitive cells. Light stimulating these cells is converted into electrical signals which are passed to the brain. The insect sees a mosiac image made up from separate bits of information entering each ommatidia. Magnification x55 at 35mm size, x110 at 6x7cm size. Microcosmos p.61 fig.3.33 Technical information: LM filtered vertical
